[New-bugs-announce] [issue18470] tokenizer.c does not handle new_string() failure

[STINNER Victor]

New submission from STINNER Victor:

Callers of the new_string() function do not check if the function succeed or not. Python does crash if the function failed, for example in get_coding_spec():

                char* r = new_string(begin, t - begin);
                char* q = get_normal_name(r);

Using pytracemalloc tool, it's easy to tricker this issue (ex: using test_future or test_parser): see issue #18408.
